Evidence on Expectations of Household Finances
利用家庭财务预期与实际变化的追踪数据，研究预期如何形成：家庭会从财务改善中推断趋势，但财务恶化时预测分歧增大，且预期错误影响储蓄和未来财务状况。
We use panel data on expected and realized changes in household finances to study the process of expectation formation. Households extrapolate from improvements in financial situation, but deteriorations are associated with an increased dispersion of forecasts, and higher probabilities of both negative and positive forecast errors. Individuals who expect earnings declines to revert too quickly save less and are more likely to be financially worse off again in the future. Learning from past errors reduces the likelihood that individuals are optimistic following a deterioration in their finances. The evidence shows how experiences, learning, and life events matter for expectation formation. This paper was accepted by Camelia Kuhnen, finance.
